Allophrys cantonensis Reshchikov & Yue , sp. nov. ( Figs 1–9 )

Diagnosis. This species is easily distinguished from other Oriental species of the genus by elongate flagellomeres ( Fig. 8 ), presence of second recurrent vein in forewing, distinctly punctate mesopleuron, and propodeal spiracle separated from pleural carina by 3.1× diameter of spiracle.

Description. Male. Body length 5.3 mm. Forewing length 2.8 mm.

Mandible with upper tooth distinctly longer than lower tooth ( Fig. 4 ). Clypeus 2.6× as broad as long, with fine and sparse punctures ( Fig. 4 ). Malar space 0.4 × basal width of mandible ( Fig. 4 ). Flagellum of antenna with 16 flagellomeres, very slender, second flagellomere 4.3×as long as broad, and subapical flagellomere 2.0× as long as broad ( Fig. 8 ). Face, frons and vertex granulate, dull or weakly shining ( Figs 3, 4 ). Compound eyes very large, rather convergent above antennae ( Figs 1– 4 ). Occipital carina mediodorsally absent.

Mesosoma very finely granulate (partly almost smooth) and indistinctly punctate, dull to weakly shining. Foveate groove of mesopleuron well developed, extending across anterior 0.7 of mesopleuron ( Fig. 5 ). Propodeum with basal area narrow, distinctly widened anteriorly, 0.4× as long as apical area ( Fig. 7 ). Propodeal spiracle separated from pleural carina by about 3.1× diameter of spiracle ( Fig. 7 ). Apical area more or less flat.

Forewing with second recurrent vein. Without brachial cell. Hind wing with nervellus slanted about 35° from horizontal.

Legs moderately slender; hind femur 5.4× as long as broad.

First tergite 11.1× as long as posterior broad, its upper margin in lateral view ( Fig. 6 ) straight in basal 0.8 and weakly rounded posteriorly. Second tergite about 2.8× as long as anterior broad.

Body mostly black ( Figs 1–9 ). Head black. Clypeus yellowish-brown. Mandible yellowish-brown, with teeth blackish-brown. Maxillary and labial palpi yellowish-brown. Antenna yellowish-brown, with flagellomeres 7–14 brown to blackish-brown ( Figs 8, 9 ). Mesosoma and first metasomal segment black. Tegula blackish-brown. Pterostigma brown. Legs yellowish-brown ( Fig. 9 ). Metasoma behind first metasomal segment brown to blackish-brown, and yellowish-brown posteriorly ( Fig. 6 ).

Female. Unknown.

Etymology. This species is named after the type locality, Canton, the Romanised name of Guangzhou.
